opus_quant_all_band_working
...n hotspot parts in this function but as this function is very much complex and its recursively called to splitting the bands I am unable to detect the hotspot part in this function. So can you guys give me some insights on optimizing any part of this function? I have tried applying wmmx simd on alg_unquant() function but its not showing any speed optimization. I am stuck in this crucial parts. Any help, insights on optimizing this function will be such a great help to me. Thanks in advance. Thanks, Karan

[Profiling][FFT][AArch64] FFT Profiling data on AArch64
Hi everyone, I have profiled Opus on AArch64. I just run opus_demo with some pcm files. Following is time proportion of FFT with different bitrate. Bitrate | Time cost by FFT/iFFT 24kb/s | 15% 48kb/s | 15% 96kb/s | 13% Any comment? I want some data close to real application, any suggestion?
